. PLOUGHS.

TO'ALL WHOM IT MAY CONGERN:

Be itiknown that I, JAMES C. DUNCAN, ofOlney, in the county ofRichlaud, and State of Illinois, have invented a new and useful improvement in Iloughs; and I do hereby declare the following to be a full, clear, and exact description of the same.

I make a plough consisting of the mould-board, land-side, and asupportiug border or sole out of a single piece of metal, the same being cut from slab steel or iron and swaged into form'while heated. I have found that by this method of construction great economy of manufacture -is attained anda substantial 'and goed article produced. l'

` In order that others skilled in the artto which my invention appcrtains may be enabled to fully understand and use the same, I will proceed to describe it in detail.

In Figure 1 of the drawings the plough is represented as attached to the beam Gr, handles M M', &c.

In Figure f2 is represented what may be termed the plough-blank, the same being cut out of slab steel or iron, and having a diamond shape or trapezoidal form, an incision being made through the blank for about half its length from the heel toward the point so as to enable the metal to be swaged or bent to form the mouldboard A and land-side B. The mould-board and land-side are thus permanently united at the forward part of the plough, and both terminate at a common point which may be made to serve the purpose'of a share. In bending the blank into shape while under heat the lower vedge of the land-side B is formed with an inwardly projecting horizontal border or sole, C, which is intended to afford a goed sliding surface, and also to keep the plough steady in operation. The heel-brace D is also formed in one piece with the mould-board and land-side,

and is bent so as to form a horizontal support or rest, D', for the plough-beam Gaus represented in iig.' 1. The rest D' may be slotted, as seen in Figure 4, to receivethe bolt I), which fastens the beam thereto, and this slot enables the beaul to be adjusted so as to take more or less land. The plough thus constructed is adapted for the attachment ot` the handles by means of bolts or otherwise, and may be braced by a bolted cross-piece at E, Figure 3, and attached to the beam G by means of the sheth F and rod H. Instead of attaching the handle M' to thc mould-board by a separate screw-bolt, the extremity of the heel-brace may be inserted through the handle and 'mould-board and riveted on the outside. lIhis plough may be made light or'heavy, according as it is designed for a cultivating or breaking plough, and it may be used singly or in gang. I, Figures 1 and 5, is a bar having a salient cutting edge, i, and fastened to the land-side by bolts or otherwise. In operation the cutting edge z' divides the rod and facilitates the work of the plough. A beard may be cut on the land-side of the point of the plough for the purpose of shielding the forward extremity of the bar I, or a separate piece, J, may be lattached. for this purpose.

Having-thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A plough embracing the mould-board A, land-side B, border or sole, C, and heel-brace D, all being united in one and the same piece or" metal, which is eut and shaped substantially as described and represented.

2. I claim the slotted rest D', when formed in one piece with the plough and employed for the support of the beam G, substantially as and for the purpose specified.

JAMES C. DUNCAN.
